CARBURETER.'

SPECIFICATION forming part of Letters lEatent/No. 633,319, dated September 19, 1899. Application tiled June 29, 1898. Serial No. 684,767. (No modem,

Be it known that I, EDWARD RAYA INMAN,

State of India-na, have invented new and useful Improvements in ACarbureters; and I do hereby declare the following to be a full, clear, and exact description of said invention, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification. 'My invention relates to improvements in carbureters. the same being a device for generating gas from crude or refined petroleumv and petroleum products when such gas is to be used as thelmotiveagent of gas and combustion engines and motors.

' In the drawings, Figure l is a vertical transverse section on line xfrof Fig. 2. Fig. 3 is a longitudinal vertical section on line y y of Fig. l. Fig. 2 is a plan view of Iny device, showing the carbureter with the cover removed. Fig. 4 is a modified form.

The same reference-figures indicate identical parts throughout the several views.

The construction of my device is substantially as follows:

My device is constructed in connection with a gas-engine cylinder l of the usual type employed in gas-engines, having the usual inletport` 2 and exhaust-port 3, together with the respective valves communicating therewith.

jacket 4.- Above the cylinder is formed the generating-chamber 5, the side Walls of which are preferably integral with the outer walls of the water-jacket. Said generating-chamberis formed by a spiral way or groove, which winds about the inside of the chamber in a continuous passage from the upper to the lower por- In the cover 7 of said chamber, and at oneendthereof, is inserted a pipe 8, 'by means of whichoil is introduced to the carbureter,

at its uppermost portion. The oil travels thence by gravity throughout the entire length of said spiral way 4to the bottom thereof and passes out through a way 9 provided therefor. In. order to vaporize the oil so introduced within the generator, heat must necessarily be there present, which heat is supplied. by the heated water in the waterspaee 4.- about the cylinder, said water becom- Iing of a sutiicient degree of heat after the engine has been in Operation for several minutes. This Water, in order to produce the best results for which it is intended-namely, the cooling of the cylinder-should be introduced into the water-jacket at a temperature not below the boiling-point of water and be discharged therefrom at a temperature of about 220:", `which degree of heat will be transmitted to thecharnber of the carbureter by radiation and the necessary. degree of heat `thereby attained As asupplementary means of heating the oil, if desirable,'the lower wall or bottom of the carbureter may be formed intact with the upper Wall of the cylinderl, and as said cylinder would become heated at this point vabove the surrounding temperature the oil as it liows along said bottoni would become heated to a muchhigher temperature than that stated. I do not-limit myself, however, to this form of construction, as an open space or water-passage may be left between the bottom of. the carbnreter and the cylinder-wall, and lby this construction the carbureter would receive its entire heat from the surrounding water.

When an engine or motor provided with my device is inoperation, the charge of gas and airis drawn into the cylinder by thefor'- ward movement of the piston, this being the usual mannei of charging all vmotors 0i the specified type; but in my device the air is passed through the carburcter and there becomes charged and mingled with the gas1 which has been expelled from the oil by the means aforesaid.

It being desirable to heat the air before it enters the carbureter the method of so heating same and its course of travel are substantially-as follows: About the exhaust-pipe 10 is formed a drum or heater l1, which heater may be a sleeve placed about said pipe, with a sufficient space between the periphery oi said pipe and the inner Wall of the sleeve to permit a passage of .a'ir through said space; Entering said sleeve and communicating from thence to the carbu reter-chamber is apipe 12. Passing out of said carbureter-chamber is an outlet-pipe i3, by means of which the airis drawn from' the chamber through the inletico Valve 1.o the cylinder. As Hic air passes stances may require in adapting mydevice to srs Athereby a suit-able and prepared vehicle for 'heat' to the carbureter I provide an opening through the sleeve it becomes heated, and

the reception of such an amount of gas as to make-it an explosive agent. The air passing .through pipe 12 the gas is mingled with it and it thence passes through pipe 13 by the way of inlet-valve into the enginecylinder and is there compressed, ignited, and exploded by the usual functions of the explosive-motor. I do not wish to=limit myself to this particular form of device, however, for heating the air before entering thecarbureter, as many other forms of device may be substituted as eircum various styles ef engines.

I am aware that other carbureters are in use for a similar purpose; but according to the best of my knowledge, information, and belief all existing -deviees employ the exhaust.- ofthe engine for heating the carbnreters. I do not, as has already been demonstrated, employ such method; but, as stated, the heat from the water surroundingr the cylinder is the principal heating agent, direct heat from the wall of the cylinder being employed as a supplementary supply when the heavier or less volatile'oils are to be utilized. The heating of the air before the same is brought into the presence of the gasI believe to be a most desirable and beneficial function and I claim the saine as a particular and valuable point of my invention.

For the purpose of applying preliminary 14 at one end of the cover, into which may be directed the llame of a torch or blowpipe and by which means the chamber of the carbureter may be brought to the desired degree of heat before oil is introduced into the carbureter for the purpose of generating sulicientgas to start the engine.

Having thus described my device, what I claim as new, and desire to secure by Letters Patent, is

l. In a earbureter for gas-engines, a carburoter-chamber formed integral with the walls i of the cylinder of the engine, substantially as and for the purpose specified. l

2. The combination with the cylinder of a gas-engine; of a water-jacket; and a carbureting-chamber provided with suitable air,

oil and gas induction and eduetion pipes, the exterior Walls of said water-jacket serving as interior walls ofv said carburetingfchamber, both chambers being adapted to be heated by the radiation of heat from said engine-cylinder, substantially for the purpose set forth.

3.y The'combination with the cylinder of a gas-engine of a carbiu'eting-chamber, provided with suitable air, oil and gas induction and eduction pipes, anda water-jacket interposed between said cylinder and a portion of the walls ofsaid carbu rctiug-chamber, whereby said earbureting-ehalnber is heated, both by the direct radiation of heat through the walls of said engine-cylinder and the indirect radiation of heat therefrom through the water in said watcrjackct, 'substantially as and for the purpose specilied.

l. ln a carbu roter for gas-engnes, a carburctiug-chan1ber, the walls of which are formed in contact with the walls of the eater-jauluet and cylinderwall, a removable cover for said chamber, an oilinlet pipe leading to said chamber, an oil-outlet pipe leading trom said chamber, and air-passage leading to said chamber, and air-heater consisting of a sleeve formed about the exhaust-pipe ot such engine, said heater forming a part ol' the passage whereby air is admitted to said carl ureting-chamber, an air and gas oulletpipe, or other suitable means connecting said car buretiug-cliamber with the inlet-port ot said gas-engine, all combined, arranged and operating substantially as shown and described.

In testimony whereof I allix my signal ure in presence of two witnesses.

EDWARD RA Y lNMAN.
